What is the role of lights on airfield vehicles?

The role of lights on airfield vehicles is primarily to increase visibility and communicate the vehicle's intent to other drivers and aircraft. This is crucial in an airfield environment where many operations occur simultaneously, and safety is paramount. Properly functioning lights enhance the visibility of vehicles, particularly in low light or adverse weather conditions, allowing other operators to see the vehicle from a distance and take necessary precautions.

Furthermore, the use of lights can signify specific actions, such as a vehicle being in motion, stopping, or indicating a turn. This communication is vital in preventing accidents and ensuring that all personnel on the airfield can operate safely and effectively. The design and use of different colored lights also serve functional purposes, indicating various statuses of the vehicle to both drivers and pilots.

While some options suggest distractions or non-functional purposes for lights, the main focus remains on safety and communication in the dynamic environment of airfield operations, making option B the most accurate reflection of their role.
